Interlogix MC251-4P/1CXT 4-Port Ethernet/PoE-af to Coax Industrial Media Converter.

These IFS 4-Port Ethernet to Coax/TP Industrial Media Converters are high-performance modules that combine two well-proven technologies---Ethernet and VDSL2--- providing a cost-effective solution for utilizing an existing telephone cable* or coax cable infrastructure when migrating from analog to an Ethernet/IP system. The MC251-4P/1CXT model provides full IEEE802.3-af (15.4w) on each individual 4 RJ45 ports and serves as a PSE device.

These modules provide plug-and-play installation and can be used in combination for either telephone cable or coax cable installations. These modules can also be used with the MCR200-1T/CX over coax only for rack mount installations at the head-end.

The one box design allows for easy set-up as either a client-side (CPE) or central-side (CO) operating device. The module is IEEE 802.3 compliant and supports multiple network protocols. In addition, the module provides on-board feature-rich diagnostic LEDs.

These IFS 4-Port Ethernet/PoE-af to Coax/TP Industrial Media Converters can extend Ethernet transmission up to .87 miles (1.4km) on standard telephone (POTS) type cable or 1.49 miles (2.4km) on coaxial cable. Performance is based on bandwidth requirements and quality of the cable used.
